What do the symbols on my Sonicare toothbrush mean?

This symbol will light up when your toothbrush has a low battery or is charging.

This symbol will light up when you need to replace your brush head. It can also flash when applying too much pressure (on some models). 

The number of lines or dots lit up refers to the intensity setting chosen. The intensity setting refers to how strongly the brush head vibrates.

The SenseIQ icon on the handle will be illuminated when the smart features are active while brushing. It will also illuminate to confirm that settings have been enabled or disabled.

Please refer to the user manual for details of the symbols on your specific model.
